What are the checks on the President from other institutions (like us, the media…)?

Answer 1

It used to be the Supreme Court but that ain't happening no mo'. The mainstream media is a joke and we've given our vote over to Diebold ( who makes the credit card readers on gas pumps and ATM's)

Answer 2

It's called voting.

Unfortunately, with less than half of the eligible voters participating, it becomes a matter of who squeaks the loudest.

Then there's the 2004 election, when people considered their options and decided they didn't want to change Horseman in mid-Apocalypse.

Me, I'm stocking up on canned goods.
